CYLlNDRlOAL-BOX MACHINE.

SPECIFICATION forming part of Letters Patent No. 782,426, dated February14, 1905.

Application filed March 16, 190 i. Serial No. 198,371.

1b and whom it may concern:

Be itknown that LWILLIAM H. S'roU'r, a citizen of the Dominion ofCanada, residing at Dayton, in the county of Montgomery and State ofOhio, have invented certain new and useful Improvements inCylindrical-Box Machines; and I do declare the following to be a full,clear, and exact description of the in vention, such as will enableothers skilled in States Letters Patent No. 706,274, granted to meAugust 5, 1902.

The pr sent improvements relate to more simplifie and reduced mechanismfor imparting to the drums the necessary horizontal reciprocatingmovements and the inter mittent and continuous rotary movements, also tomeans for holding the bottoms and tops of the boxes in positions duringthe operations of forming the boxes, and further improvements relate toan inclosinghood for the drums, which is instrumental in holding theveneer in position during the operations of forming the boxes, and otherfeatures hereinafter more fully described in the followingspecification.

Preceding a detail description of the invention reference is made to theaccompanying drawings, of which- Figure 1 is a front elevation of themachine. Fig. 2 is a rear elevation of the same. Fig.

3 is an end elevation of the same. Fig. 4 is a section on the line a:wolf Fig. 1. Fig. 5 is a section on the line 3/ y of Fig. 1. Fig. 6 is asectional view of a portion of the removable top drum, which holds thetops of the boxes in position while in operation. Fig. 7 is an enlargeddetail cross-sectional view of the inclosing hood. Fig-8 is an enlargeddetail view of the hood inah open position. Fig. 9 is an enlarged detailview of a portion of the feeding mechanism.

the bases 2' of which slide in ways in the stationary frame of themachine. Pivotally connected tothe slidable bearings 2 2 are rocker-arms3 3. To these rocker-arms there are connected rods 4 4, which in turnare con nected, by means of wrist-pins, to spur-whcels 6 ii, the saidspur-wheels serving as cranks in this connection, from which therocker-arms are oscillated. The spur-wheels 6 6 are retated to impartsuch movements from a piir ion 7 on ashaft 8, lying at right angles tothe plane of the machine, and has hearings in said frame. as shown inFig. 5. The shaft 8 is driven through a miter-gear 9 thereon which isengaged by a smaller miter-gear 10 "on shaft 11, the latter being themain powershaft which is driven by a pulley 11', the latter being beltedto the driving power-shaft. (Not shown.) The power transmitted fromshaft 11 to shaft 8 is controlled bya clutch 17 on shaft 8, which ismovable in and out of engagement with the miter-gear 9 by handoperating-lever 12, which is fulcrumed on shaft 13 and is connected withthe clutch 17 by shifting lever 16, connecting-link 15, and arm 14., thelatter being an extension from the operating-lever 12. v

The rotary movements are imparted to the drums 1 1' through thefo'llowing'mcchanisms: The enter ends of said drums i i have lixcdthereto spur-wheels 40. which gear with pinions 39 on shaft 38. Thesepinions, as well as the spur-wheels 40, are splined upon theirrespective shafts and are therefore rotated by said shafts and arepermitted to have sliding movements along said shafts when the slidablcbearings 2 2 are given the horizontal reciproeating movementshereinbefore described. From Figs. 1 and 2 it will be seen that thepinions .39 have their boxes connected with the upper ends of thebearings 2 2. The shaft 38 is given intermittent rotary movement formthe main power-shaft 11 through acrankdisk 21, to which the lower end ofconnectingrod 31 is pivoted. The shaft 20, to which the disk 21 isrigidly attached, is driven from the main power-shaft 11 throughspurwheels 18 19, the latter wheel being controlled by a clutch 22 onthe shaft 20, wheel 19 being also on the same shaft. The clutch 22 isoperated to be thrown in and out of gear by a handlever 23, which isconnected to a shifting lever 26 on shaft 26' and is attached to saidclutch by connecting-links 24 25. (See Fig. 1.) The connecting-rod 31 isconnected at its upper end to the rock-shaft 33 by a crankarm 32. Poweris transmitted from shaft 33 to shaft 38 through connecting-rod 35. Theupper end of this connecting-rod 35 is connected to the shaft 33 by anarm 34 and an adjustable yoke 35, which is pivoted to the connecting-rod35, and is moved to the proper position on the arm 34 and is thensecured by a set-screw. (See Fig. 4.) 36 is a pawlsupport pivoted to thelower end of rod 35 and carrying a pawl 36', which engages aratchet-wheel 37, fast on shaft 38. It will be seen that intermittentmovement is transmitted to the shaft 38 from the power-shaft 11 andthence to the drums l 1' through the spur-wheels 39 and 30, hereinbeforereferred to. During this intermittent rotary movement the sheets ofveneer are fed into the machine and the nailing operations take place,said nailing operations occurring at each stop of the drums through thefollowing mechanism. (See Fig. 5.) 42 represents adjustableconnecting-rods which are pivoted to arms 41, fast upon the rocker-shaft33. The lower end of rods 42 have fixed connections with avertically-slidable support 43, in which the naildrivers 44 are held.The nails 52 are placed in a hopper 71, which is hinged at its front toa support 72, and the bottom of which is provided with a number ofparallel slots through which the nails project and are suspended, asshown in Fig. 5. The hopper is supported in an inclined position and 'isvibrated to cause the nails to travel therein by means of a lever 73,which is hinged at 74 to the crosssupport 64, and has a pivotalconnection with a lever 75, which is pivoted at 76 to the slidablesupport 43. Extending forwardly from said hopper areaseries of chutes65, which are connected at their forward ends to a crosssupport 64. (Seealso Figs. 6 and 7.) The chutes have slots or passages 66 extendinglongitudinally through them, through which the nails pass downwardly andare suspended therein by their heads. (See Fig. 10.) Below the forwardends of these chutes and attached to the supports 64 are a series ofeasings 67, which support the nail-separators. (Not shown.) 59 is areciprocating r 0d operating the nail-separators and which isconnected,at suitable points to said separators by cranks 62, which arefixed to the journals 63 of the separators and have pivotal connectionswith sleeves 60 on said-rod, said sleeves being held firmly at one endby collars and at the other end they are held yieldingly by coilsprings61. parted to the rod 59 from a slidable support 43, as follows: On saidsupport there are two antifriction-rollers 53, which inclose a cambar54, pivoted at its upper end to a rigid arm 54', which is attached tothe support 64 at one end and to the upright frame at the other end. Thelower portion of the cam-bar 54 has a suitable bend to impart thenecessary movement to a lever 56. The lower end of said cam-bar isconnected to the lever 56 by a pivotal link 55, said lever beingfulcrumed at 57 and having its upper end pivoted at 57 to link-lever 58,which in turn is pivoted to one of the sleeves 60 on rod 59. It willthus be seen that in the vertical movements of the slidable support 43longitudinal movement will be imparted to the rod 59 to move it in onedirection and in the reversed direction. After the .veneer cylinder hasbeen formed and united to the bottoms and tops and at the center of eachbox the rotary movement is changed from an intermittent movement to acontinuous movement, during.

which the cylinder is sawed through at both ends and at the centers toconstruct two boxes from each cylinder thus formed. This con tinuousrotary movement is transmitted by the following mechanism: 93 designatesa shaft which is driven from the main powershaft 11 through gears 18 1919', the latter gear being loose on said shaft and controlled by aclutch 30, which is operated from a lever 27, connected to a shiftinglever 27' on shaft 26' by links 28 and 29. The shaft 93 carries a pinion93', which gears with the spur-wheel 40 on drum 1. hen the shaft 93 isthrown in gear with the power-shaft 11, it will be understood that theshaft 33 is idle, having performed its operations. Shaft 38 is drivenfrom the drum-gear 40. The gear 39 on the opposite end of said shaft 38drives the drum 1' at the same rate of speed as adjacent drum 1 isdriven, and a continuous movement is imparted to both drums. I will nowdescribe the sawing mechanism which is operated during this period.Before power is put into shaft 93 the saw-frame 86, which swings onshaft 87, is moved into operative position to bring the saws in contactwith the box-cylinder by means of a hand-lever 91, which is fulcrumedupon shaft 13 and is connected to the saw-frame 86 by a lever 92, whichconnects with the crank end 91' of said hand-lever and also with thesaw-frame at point 93. Shaft 87 is mounted in bearings 87" and is drivenfrom the main power-shaft 11 by pulleys, one of which, 87', is shown inFigs. 2 and 5.

Reciprocating movement is im- 50 is coupled to lever 80 by a link 81'.

90 designates the two end saws and three center saws, mounted upon amandrel 89 in the upper end of the swinging frame 86. The saw-mandrel 89is driven from shaft 87 by a belt 88, passing around pulleys on saidshafts.

The two end saws are adjustable along the shaft to proper points to cutthe ends of the boxes, and the central saws separate the lids from theboxes. One complete revolution of (o the drums is required to cut theboxes to their respective sizes, after which the power is shut off, andthe drums are withdrawn from the cylinder by the outward movement ofsaid drums by throwing into gear the clutch 17.

The independent central drum 77 is'removed with the boxes, after whichsaid boxes are detached from said drum, and the disk portion forming thetops 95 are then detached from said drum. In assembling the lid-drum 2o77 with the box-tops 95 a suitable number of spurs 94 are employed,which temporarily hold said tops in positions atthe ends of the lid-drum77. Against the outer sides of the tops 95 thin rings 96 are placed,having a suitable number of spurs which hold the bottoms 95 of the boxesin positions against the tops 95. The rings 96 provide suitable spacefor the entrance of the two outer middle saws 90 in severing the boxes.When the bottoms 3o 95' and tops 95 are thus assembled with the drum 77,the said drum is placed in a central position within a hood and restsupon springpads'85 in said hood. (See Figs. 13 and 14.) This hood holdsthe drum 77 in a central position -to meet the box-drums 1 1- as said 0pads 85. For a more detailed description of the hood reference is madeto Fig. 14,where it will be seen to consist of three parts. The rearwardpart 78 is stationary in the machine, a bottom part 78' hinged to 78 at79', and. a

forward part 78" hinged to the part 7 8' at 79.

These hinged portions 78 and 78" are oper- "ated upon their hinges toopen and close, as follows: 82 is a lever fulorumed at 83 to astationary portion of the frame. This lever 80 is fulerumed at 81 to theframe, and upon this lever 80 the hinged portions 7 8' and 78" of thehood are supported or held, said parts of the hood resting upon saidlever when in their lower position, as shown in Fig. 15, the

, said lever 80 holding said parts up when elevated to a closedposition, asshown in Fig. 5. The back portion 78 of the hood is held inposition by a grooved ring 78'. (See Fig. 3.)

There is one of said grooved rings in each of the upright portions ofthe frame, which is instrumental in stripping the boxes from the drumsin the downward movement'of said drums. These rings are fullyillustrated and described in my former patent.

Lever The function of the hood thus above described is to prevent theincoming veneer from bulging out from the drums as it is fed around saiddrums. In other words. its function is to keep the veneer in suitableproximity to the drums in the operations of forming the cylinders fromwhich the boxes are constructed.

Having described the various essential features of my invention, I willnow (let-ail briefly a description of its operation. The sheets ofveneer are out to the proper sizes and are laid upon the feed-table 94,properly assembled and united with the parts that form the bands. Theveneers are moved into a point where they are caught by the lip 95,which is on the center drum 7?. (See Fig. 5.) hen in this position, thenailers unite the veneer to the tops and bottoms 95 95, as shown in Fig.13.- The nailing devices are the subject-matter of another applicationfor Letters Patent. The drums being rotated intermittently, ashereinbefore described, the veneers are naiied around said tops andbottoms until one com plote revolution of the drums is made. The nailingmechanism is then stopped by throwing out of gear the shaft 20 by lever27, and shaft 93 is thrown in gear by its respective lever 27. The sawshaving been moved into operative position with relation to the drums bylever 91, said drums are given one complete and continuous rotation fromshaft 93, during which the cylinder formed upon the two drums is cut tothe respective sizes to complete two boxes. The power is then out offfrom shaft 93 and the hood 78 is lowered, after which the drums 1 1 arelnoved out" wardly by lever 12, throwing in operation the clutch 17, andthe boxes are removed from the'hood.

Having described my invention, I claim 1. In acylindrical-box machine,the combination with end drums, of an independent central drum whichsupports the disk portions of the boxes, and a hood partially inclosingsaid drums. said hood consisting of hinged sections one of which isstationary, and means operati vely connected with the other portions ofsaid hood for opening and closing the same.

2. In a cylindrical-box machine, the combi' nation with two end drums,of an independent central drum interposed between said end drums, meansfor temporarily uniting dish portions of the boxes with said centraldrum, and means interposed between the end drums and said disk portionswhereby the central drum is rotated during the formation of boxes.

3. In a cylindrical-box machine, two end drums, an independent centraldrum interposed between said end drums, said central drum supportingdisk portions of the boxes to be formed, a hood consisting of sectionswith'hinged oonneotiona the rearward section being stationary, openingsin the body of said hood, and spring cushions projected through saidopenings and adapted to support said central drum. i

4. In a cylindrical-box machine, the combination of a drum having meansat each end adapted to engage and rotate disk portions of boxes to beformed, a hood inclosing said drum, and means whereby said drum may berotated by power communicated through said disk portions.

5. In a cylindrical-box machine, the combination with end drums uponwhich boxes are formed, an independent central drum which supports diskportions of the boxes during the operation of forming said boxes, meansfor severing the cylinders formed upon said drums into boxes, and a hoodinclosing said drums, said hood being in hinged sections which areopened to admit of the removal of the boxes with the central drum.

6. In a cylindrical-box machine, an independent central drum, means forsupporting the disk portions of the boxes on the ends of said drum,means whereby said drum may be rotated by power communicated throughsaid disk portions, and a hood inclosing said drum and holding it inposition.

7. In a cylindrical-box machine, the combination of end drums, anindependent central drum, means for temporarily uniting disk portions ofthe boxes to the ends of the said central drum, and independent ringswith oppo: sitely-extending spurs which unite the boxes to said diskportions and whereby power is transmitted from the end drums to thecentral drum during the operations of forming the boxes.

In testimony whereof I affix my signature in presence of two witnesses.
